==How To Watch The Token Contract In Ethereum Wallet / Mist==
In Ethereum Wallet / Mist, select the '''CONTRACTS''' tab and click '''WATCH CONTRACT''' to open the Watch contract window. Then:

* Under '''CONTRACT NAME''', enter '''SNGLS'''
* Under '''CONTRACT ADDRESS''', enter '''0xaec2e87e0a235266d9c5adc9deb4b2e29b54d009'''
* Copy the Application Binary Interface below and paste it into the '''JSON INTERFACE''' text box

<syntaxhighlight lang="javascript">

* Click '''OK'''

==How To Watch The Token In Ethereum Wallet / Mist==
In Ethereum Wallet / Mist, select the '''CONTRACTS''' tab and click '''WATCH TOKEN''' to open the Add token window. Then:

* Under '''TOKEN CONTRACT ADDRESS''', enter '''0xaec2e87e0a235266d9c5adc9deb4b2e29b54d009'''. The additional fields should automatically be filled in.

* Click '''OK'''

==Check Your Token Balance In EtherScan.io==

Navigate to https://etherscan.io/. Then:
* Select the menu '''TOKEN''' -> '''View Tokens'''
* Select '''SNGLS - SingularDTV'''
* Select the '''Read Contract''' tab
* In the '''balanceOf''' field, enter the address you want to check the token balance of
* Click '''Query'''

A simpler way to check your token balance is to navigate to https://etherscan.io/. Then:
* Enter your address into the search box on the top right of the screen
* Press '''ENTER'''
* Click on the '''View Token Balances''' dropdown

==How To Interact With The Token Smart Contract In Ethereum Wallet / Mist==

===How To Check Your Token Balance In Ethereum Wallet / Mist===

[[#How To Watch The Smart Contract In Ethereum Wallet / Mist|Watch the Contract]] and [[#How To Watch The Token In Ethereum Wallet / Mist|Watch the Token]] as described above. Then:
* View the '''SNGLS''' contract
* Click on '''SHOW CONTRACT INFO'''
* In the '''READ FROM CONTRACT''' section and under '''Balance of''':
** Enter the address you want to check the token balance of
** The token balance will be displayed in the [[Natural Units]] with 0 decimal places. e.g., 12345 = 12345 token units

===How To Transfer Your Tokens In Ethereum Wallet / Mist===

[[#How To Watch The Smart Contract In Ethereum Wallet / Mist|Watch the Contract]] and [[#How To Watch The Token In Ethereum Wallet / Mist|Watch the Token]] as described above. Then:
* View the '''SNGLS''' contract
* Click on '''SHOW CONTRACT INFO'''
* In the '''WRITE TO CONTRACT''' section and under '''Select function''':
** Select the '''Transfer''' function
** Under ''to'', enter the address you want to transfer your tokens to
** Under ''value''', enter the amount of tokens you want to transfer. This amount needs to be specified in the [[Natural Units]] with 0 decimal places. e.g., 12345 is 12345 SNGLSs
** Under '''Execute from''', select the account you want to transfer your tokens from
** Click on '''Execute''', then confirm your transaction
